Im glad you liked it! Yes I thought we could use a better tutorial but we were running out of time. Also, yes there is an exit button but something happened on a github merge that broke the button that moves you from level 3 to level 4, if that is what you're talking about. if you want to play level 4 and level 5 you have them from the level select :/ we didn't notice this until it was too late to re submit.
